Galaxy Note 3 red line on white wallpaper

Hi! i noticed my Note 3 has a red / purple line on the bottom of the screen,i see it when access *#0*# menu. Is like a red/purple very thin shadow, seen on White background. Is a AMOLED "feature" ? You have that on your Note 3?

mine doesn't have anything like that, very uniform white, top to bottom. Could the screen be miss aligned and the very last row of green subpixels too low to be visible to offset red blue and therefore giving red/purple hue? But since it's on the very bottom I wouldn't worry about it too much even if I had it.

The diamond PenTile matrix is responsable for some chromatic aberation. As said ReNeH99, the two green subpixels are to blame. For example, if you look very carefully at the top of the display on white wallpaper, you see the first row of pixels are fade in green/blue shadow, but less vissible then the lower red/purple fade.
I attached the pen tile matrix used in Note 3 display.
